Boxtream
is a GPL-licensed streaming video and audio system that is being
developed by Jerome Alet and a
team of developers at the University of Nice in France:
Boxtream is a mobile and autonomous audio and video streaming and recording studio. Of course, depending on your own hardware choices, the number and extent of capabilities and the quality of the final results may vary, but at least the software part should be versatile enough to accommodate even the most basic hardware.
Boxtream was mostly designed to stream live courses featuring a professor and his slides (or any other computer based output like software training, web browser, video player...), but can also be used to stream congresses, interviews and the like.
Boxtream uses a virtual smorgasbord of open-source components to achieve
its results. Scripting is done with the Python language, metadata is
stored in the XML format.
The GStreamer
multimedia framework library is used for handling the audio/video
data and the
Icecast streaming media
server is used for media distribution.
Video and audio are encoded with
Ogg Theora and
Ogg Vorbis. The
Graphviz graph visualization
software is used for presenting a graphical view of the video
system's scenario.
A few notable Boxtream features include a GUI interface, support for
on-disk recording, selectable audio and video rates, support for
image overlays and automation for all tasks.
The Boxtream
features
list has a more complete list.
Boxtream supports a number of video switching devices as well as other
video and audio equipment. The
hardware
list has more information.
This
architecture diagram gives a pictorial view of a fairly complicated
Boxtream system. An online
example
shows the system being used for a scientific conference.
Boxtream version 0.998 was
announced
on April 27, 2008.
Changes include support for more video hardware, inclusion of the dia
schema software, bug fixes and a license change from GPLv2 to GPLv3.
If your organization is in need of a full-featured video conferencing
system, you should give Boxtream a look.

Database Software
Sub-release 2.0.4 of the Firebird DBMS has been
announced.
"
Several important bugs have been fixed, including a number of unregistered nbackup bugs that were found to cause database corruptions under high-load conditions.
During Firebird 2.1 development it was discovered that Forced Writes had never worked on Linux, in either the InterBase or the Firebird era. That was fixed in V.2.1 and backported to this sub-release.
The issue with events over WNet protocol reported below for v.2.0.3 has been fixed."

Three patches have been released for
Kexi, a KDE visual database
design tool.
"
Dear users,
As there are no new releases of KOffice in 1.x series, we're providing
important maintenance patches from time to time. These patches are especially
recommended for Linux/Unix distributions: in order to maintain high quality of
the software, packagers should apple them before building."

Interoperability
A new newsletter that covers the Samba world has released its first issue. It is planned to be bi-weekly (fortnightly for those of a UK persuasion). It will summarize mailing list threads and cover recent events affecting the Samba community. "
Several of Samba team members agreed during discussions
held at Samba XP (see article #3) that periodic thread
summaries from the recent development activities would
be helpful for keeping the community and Samba OEM vendors
up to date. So using editorial privilege, I've decided to
term these as mashup reports." Click below for the full issue.

replaces the print plug-in packaged with the GIMP distribution."

FreeIPA is an integrated security information management solution
combining Linux (Fedora), Fedora Directory Server, MIT Kerberos and NTP.
FreeIPA binds together a number of technologies and adds a web interface

management with plans to support policy and auditing management.
We were able to achieve most of the planned features for this

very happy about the outcome."

Python
Python PEP 3108 has been announced.
"
Just like the language itself, Python's standard library (stdlib) has
grown over the years to be very rich. But over time some modules
have lost their need to be included with Python. There has also been
an introduction of a naming convention for modules since Python's
inception that not all modules follow.
Python 3.0 has presented a chance to remove modules that do not have
long term usefulness. This chance also allows for the renaming of
modules so that they follow the Python style guide [#pep-0008]_. This
PEP lists modules that should not be included in Python 3.0 and what
modules need to be renamed."

Version Control
Ben Collins-Sussman has posted
an interesting note on the
future of Subversion and centralized version control. "
I've
chatted with other developers, and we've all come to some similar private
conclusions about Subversion's future. First, we think that this will
probably be the 'final' centralized system that gets written in the open
source world - it represents the end-of-the-line for this model of code
collaboration. It will continue to be used for many years, but specifically
it will gain huge mindshare in the corporate world, while (eventually)
losing mindshare to distributed systems in the open-source arena."
